Abstract (en)
[origin: WO2020204793A1] The present invention relates to a method for extracting hemicellulose from lignocellulosic material, the method comprising - providing (11) a quantity of lignocellulosic material comprising a first amount of hemicellulose, - determining (12) a desired amount of hemicellulose for extraction, wherein the desired amount of hemicellulose is determined (12) as a portion of the first amount of hemicellulose, - supplying (13) the lignocellulosic material to the treatment vessel, - performing (14) hydrolysis of the lignocellulosic material for extracting hemicellulose, and - supplying (15) a volume of displacement liquor, wherein the volume of displacement liquor is supplied until the desired amount of hemicellulose is displaced from the treatment vessel.
